Hiding and showing stylus pop-up menu items

To hide and show stylus pop-up menu items, use the method CAknStylusPopUpMenu::SetItemDimmed() in the
class.

// You can remove the menu item dynamically according to the command id. For example:
iPopupMenu->RemoveMenuItem( StylusMenuCommand1 );
// You can dim (hide) a menu item without removing it
iPopupMenu->SetItemDimmed( StylusMenuDynamicAdd, ETrue );
// You can un-dim(show) the menu item again:
iPopupMenu->SetItemDimmed( StylusMenuDynamicAdd, EFalse );
